TACO keeps flipflopping, but each time Russia ends up with an advantage. Random noise should average to zero. When it averages in one party's favour, it's not noise.
They are fighting against a country with something like 1/5th of their population so this reasoning is completely fallacious. You will use any advantage gained by Russia as evidence of collusion without demonstrating that the advantage was based on collusion. The intelligence agencies have tried and failed to prove this theory of Russian infiltrationism for more than 10 years now; you haven’t seen something that they’ve missed.
